Hi Jean. Certainly in our garden they dive headlong into bushes or trees & what happens is exactly as you describe, birds fly out in all directions. We have also watched a sprawk hopping around inside the bush & a small bird hopping around in the same bush, trying to keep as far away as possible without heading out. If the small bird then makes a dash for it the sprawk is often right on it's tail very fast.
